logback如何自定义日志存储
作者：吾追无所求
这篇文章主要介绍了logback如何自定义日志存储的操作，具有很好的参考价值，希望对大家有所帮助。如有错误或未考虑完全的地方，望不吝赐教
logback自定义日志存储
1、配置lockback.xml
<?xml version="1.0" encoding="UTF-8"?>
<configuration>
<property name="LOG_HOME" value="/wzwsq-log" />
<property name="APP_NAME" value="wzwsq" />
<!-- 控制台输出 -->
<appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
<encoder class="ch.qos.logback.classic.encoder.PatternLayoutEncoder">
<!--格式化输出：%d表示日期，%thread表示线程名，%-5level：级别从左显示5个字符宽度%msg：日志消息，%n是换行符 -->
<pattern>%d{yyyy-MM-dd HH:mm:ss.SSS} %X{address} %-5level %logger{50} - %msg%n</pattern>
</encoder>
</appender>
<!-- 按照每天生成日志文件 -->
<appender name="FILE" class="ch.qos.logback.core.rolling.RollingFileAppender">
<rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
<!--日志文件输出的文件名 -->
<FileNamePattern>${LOG_HOME}/${APP_NAME}.log.%d{yyyy-MM-dd}.log</FileNamePattern>
<!--日志文件保留天数 -->
<MaxHistory>10</MaxHistory>
</rollingPolicy>
<encoder class="ch.qos.logback.classic.encoder.PatternLayoutEncoder">
<!--格式化输出：%d表示日期，%thread表示线程名，%-5level：级别从左显示5个字符宽度%msg：日志消息，%n是换行符 -->
<pattern>%d{yyyy-MM-dd HH:mm:ss.SSS} %X{address} %-5level %logger{50} - %msg%n</pattern>
<!--<pattern>%-4relative [%thread] %-5level %logger{35} - %msg%n</pattern> -->
</encoder>
</appender>
<!--连接数据库配置 class：日志保存操作类 -->
<appender name="db_classic_mysql_pool" class="wzwsq.config.LogDBAppender">
<connectionSource class="ch.qos.logback.core.db.DataSourceConnectionSource">
<dataSource class="org.apache.commons.dbcp.BasicDataSource">
<driverClassName>com.mysql.jdbc.Driver</driverClassName>
<url>jdbc:mysql://localhost:3306/wzwsq?serverTimezone=GMT%2B8&useSSL=false&characterEncoding=utf8</url>
<username>root</username>
<password>123456</password>
</dataSource>
</connectionSource>
</appender>
<!-- 日志输出级别 -->
<root level="info">
<appender-ref ref="STDOUT" />
<appender-ref ref="FILE" />
<!--添加自定义操作配置-->
<appender-ref ref="db_classic_mysql_pool" />
</root>
</configuration>
2、配置自定义日志操作类
import ch.qos.logback.classic.spi.CallerData;
import ch.qos.logback.classic.spi.ILoggingEvent;
import ch.qos.logback.core.db.DBAppenderBase;
import com.alibaba.fastjson.JSONObject;
import wzwsq.model.IpInfo; //自定义IP对象
import wzwsq.model.UsersModel; //自定义用户对象
import wzwsq.util.Constant; //自定义常量对象
import wzwsq.util.WebUtils; //自定义Web工具对象
import org.springframework.context.annotation.Configuration;
import java.lang.reflect.Method;
import java.sql.Connection;
import java.sql.PreparedStatement;
import java.sql.SQLException;
import java.sql.Timestamp;
/**
* @ClassName LogDBAppender
* @Description: 自定义日志保存至数据库
* @Author wzwsq
* @Date 2020/12/10
* @Version V1.0
**/
@Configuration
public class LogDBAppender extends DBAppenderBase<ILoggingEvent> {
protected static final Method GET_GENERATED_KEYS_METHOD;
//插入sql
protected String insertSQL;
//自定义存储字段
/**
* menu_type：操作类型，指的是菜单ID
* record_id:相关操作对象的ID
* operation_content：操作内容，自定义编辑
* add_id：操作人ID
* add_time：操作时间
* ip：根据IP对应城市
* city：ip所属城市
* ua：浏览器信息
* */
static final int MENU_TYPE = 1;
static final int RECORD_ID = 2;
static final int OPERATION_CONTENT = 3;
static final int ADD_ID = 4;
static final int ADD_TIME = 5;
static final int IP = 6;
static final int CITY = 7;
static final int UA = 8;
static final StackTraceElement EMPTY_CALLER_DATA = CallerData.naInstance();
static {
// PreparedStatement.getGeneratedKeys() method was added in JDK 1.4
Method getGeneratedKeysMethod;
try {
// the
getGeneratedKeysMethod = PreparedStatement.class.getMethod("getGeneratedKeys", (Class[]) null);
} catch (Exception ex) {
getGeneratedKeysMethod = null;
}
GET_GENERATED_KEYS_METHOD = getGeneratedKeysMethod;
}
@Override
public void start() {
// 将写好的sql语句赋值给insertSQL
insertSQL = buildInsertSQL();
super.start();
}
// 自己写新增sql语句
private static String buildInsertSQL() {
return "INSERT INTO `operation_log`" +
"(" +
"`menu_type`,`record_id`," +
"`operation_content`,`add_id`," +
"`add_time`,`ip`," +
"`city`,`ua`" +
")" +
"VALUES (?,?,?,?,?,?,?,?)";
}
@Override
protected Method getGeneratedKeysMethod() {
return GET_GENERATED_KEYS_METHOD;
}
@Override
protected String getInsertSQL() {
return insertSQL;
}
/**
* 主要修改的方法
*
* @param stmt
* @param event
* @throws SQLException
*/
private void bindLoggingEventWithInsertStatement(PreparedStatement stmt, ILoggingEvent event) throws SQLException {
// event.getFormattedMessage() 日志打印内容
String message = event.getFormattedMessage();
// 如果只想存储自己打印的日志，可以这样写日志：
// logger.info("'MENU_TYPE': '{}','RECORD_ID': '{}','OPERATION_CONTENT': '{}'",XXX,XXX,XXX)
//判断当前日志信息是否属于自定义类型
int MENU_TYPE_FLAG=message.indexOf("MENU_TYPE");
int RECORD_ID_FLAG=message.indexOf("RECORD_ID");
int OPERATION_CONTENT_FLAG=message.indexOf("OPERATION_CONTENT");
if(MENU_TYPE_FLAG>0&&RECORD_ID_FLAG>0&&OPERATION_CONTENT_FLAG>0){
//截取用户自定义的日志信息
JSONObject jsonObject =JSONObject.parseObject(message);
String menuType=jsonObject.get("MENU_TYPE").toString();
String recordId=jsonObject.get("RECORD_ID").toString();
String operationContent=jsonObject.get("OPERATION_CONTENT").toString();
//获取当前使用系统的用户对象、IP、CITY、UA
UsersModel usersModel=WebUtils.getUser();//用户登录对象
IpInfo ipInfo=(IpInfo)WebUtils.getSession().getAttribute(Constant.IP_INFO);//用户登录IP信息
String ip=ipInfo.getIp();
String city=ipInfo.getCity();
String ua=ipInfo.getUa();
stmt.setString(MENU_TYPE, menuType);
stmt.setString(RECORD_ID, recordId);
stmt.setString(OPERATION_CONTENT, operationContent);
stmt.setString(ADD_ID,usersModel.getId().toString());
stmt.setTimestamp(ADD_TIME, new Timestamp(event.getTimeStamp()));
stmt.setString(IP, ip);
stmt.setString(CITY,city==null?"":city.toString());
stmt.setString(UA, ua==null?"":ua.toString());
}
}
@Override
protected void subAppend(ILoggingEvent eventObject, Connection connection, PreparedStatement statement) throws Throwable {
bindLoggingEventWithInsertStatement(statement, eventObject);
// This is expensive... should we do it every time?
int updateCount = statement.executeUpdate();
if (updateCount != 1) {
addWarn("Failed to insert loggingEvent");
}
}
@Override
protected void secondarySubAppend(ILoggingEvent eventObject, Connection connection, long eventId) throws Throwable {
}
}
3、调用方法
private static Logger logger = LoggerFactory.getLogger(UsersController.class);
logger.info("'MENU_TYPE': '{}','RECORD_ID': '{}','OPERATION_CONTENT': '{}'",XXX,XXX,XXX);
注意事项：在logback.xml中appender标签一定的写在root标签之前
